MUHAMMAD ALI KHANZADA, ABDUL MUBEEN LODHI AND SALEEM SHAHZAD
Abstract
Mango plantations in different areas of Sindh were found to suffer from a decline disease showing symptoms of drying of branches from the tip accompanied with a heavy exudation of yellowish-brown gum from stem and its branches and browning of vascular tissues. Under severe conditions, the disease results in death of the plant. There was an invariable association of Lasiodiplodia theobromae with aerial as well as underground parts. Fusarium solani was mostly isolated from root but very rarely from the stem. Inoculation of healthy plants with L. theobromae either alone or in combination with F. solani produced typical symptoms whereas F. solani failed to produce these symptoms.
